The Spain Visit Visa allows stays of up to 90 days in Spain, and other Schengen countries, within a 180-day window. Visitors can spend no more than 90 days in the Schengen area during any 180-day period. Staying longer than permitted may lead to penalties, fines, or declined visa applications in the future. If longer stays are planned, a long-stay visa or residence permit should be obtained, based on the visit's purpose.
